"IBM presents the sixth generation of IBM Ultrastar 10,000 rpm disk drives. The IBM Ultrastar 146Z10 drive family offers high quality and superior performance. These drives feature more powerful processors and read/write channels to excel in server-class environments. To achieve maximum I/O performance, the drives combine fast seek times, large 8 MB multi-segmented buffers, a sophisticated command queuing algorithm, hardware automation, and superior data rates (825 Mbps). Ultrastar 146Z10 drives include a servo technology (Rotational Vibration Safeguard ""RVS""), employed to counteract the effects of rotational vibration that commonly occur in multi-drive cabinets. They also employ a fifth-generation giant magnetoresistive (GMR) head technology to double areal density from previous generation drives (26.3 Gbits/sq.in.) and boost performance. In addition, highly efficient No-ID sector formatting enables more data to be stored per disk.Feature Value Header / Product Line  IBM UltraStar  Header / Model  146Z1"Minimize
